Hi all, I am trying to deploy simplex with IPv6 environment, and fail at openstack application apply. It is due to pod "mariadb-ingress" fail to become ready. Here is the failure in the pod log: " Warning Unhealthy 142m kubelet, controller-0 Readiness probe failed: dial tcp [fd03::1e6d:6abe]:3306: connect: connection refused " And container log shows below error: " [emerg] 95#95: invalid port in upstream \"fd03::1e6d:6aac:3306\" in /tmp/nginx-cfg026066192:332 " The ISO I used is cengn 10/18 build, which pass sanity test. Does anyone try IPv6 deployment recently? And do you know what cause upper failure? Thanks. More log and my configuration info is attached in below link. http://paste.openstack.org/show/785508/ Best Regards Shuicheng
